AppiiationyNovember 1s, "1931, serial 10.574367 ,My invention relates to improvementsin electric calendar clocks, and it has [particular relation to novelv means vfor indicating lunar conditions? and month and 'year dates in addition to the provision of means for indicating the hours, minutes, days of the week and day of the month.

Of the means above mentioned, all except the means for indicating lunar conditions and month and year dates have been embodied in my pending application Serial No. 468,966, filed July 18,

An object of the invention is the provision of novel means for bringing various parts of a calendar clock mechanism into operative indicating positions.

A further object is the provision of novel mechanism whereby various dials and a web are brought into cooperative relationship in a calendar clock.

For a better understanding of my invention yreference may now be had to the accompanying drawings forming a part of this disclosure where- 1n:

Figure 1 is a front elevational View, partly broken away, of a clock embodying the novel features of my invention;

Figure 2 is a sectional ing with the enclosed shown in elevation;

Figure 3 is a front elevational view of the clock 80 with portions broken away to disclose parts of the operating mechanisms; and

Figure 4 is an enlarged detail View of a portion of the structure shown in Figure 1 to illustrate the lunar dial.

The embodiment of my invention illustrated in the accompanying drawings, broadly considered, comprises a clock housing 1 mounted upon a base portion 2. Within the housing is slidably mounted a clock casing 3 to which is permanently aflxed an electro-motor operated clock mechanism of conventional design, as indicated generally at 4, and driven by a motor 4a, having the usual plug connection 4b and wiring 4c. Also permanently mounted in 'the casing, but separated by a plate 5 from the clock mechanism 4,

view through the casoperating mechanism is the driving mechanism for the applicants improved lunar condition indicating device. This driving mechanism is mounted in a space provided between the plate 5 and a clock face 6 which is attached to the plate by means of a sef ries of arms 7.

The driving mechanism for the lunar condition indicating device consists of a main shaft 8 projecting through the plate 5 and the face 6 and carrying a single-toothed gear 9 which is mounted on the shaft 'andmeshes with a V24-i,'ooi;'1f1ed gear 10,V mounted 'upon yal shaft ,11. The. `sha.ft" ,1`1 v also carriesa pair of single-toothed gearsA 12,

13 respectively. The gear'lZ meshes with a 28- vtoothed gear 14 mounted upon a shaft 15. The 5 gear 13 meshes with a 35toothed gear 16 revolubly mounted upon the main shaft 8 and having a hub portion 17 which projects through the face 6. Mounted on the main shaft 8 on the motor side of the plate 5 is an 8-toothed gear 18 mesh- 10 ing with a 32-toothed gear 19 mounted upon a' shaft 20 projecting through the face 6. The shaft 20 also carries a 10-toothed gear 21 meshing with a -toothed gear 22 mounted on a shaft 23 which projects through the clock face 6.

A dial 24 is mounted upon the outer end 0f the shaft 15 and upon the dial is shown a representation of a full moon 25 having a background of stars 26. An irregularly shaped opening 27 is provided in the face 6 and registers with the 20 dial 24 so that the moon 25 will be visible in its various stages by reason of its full or partial exposure through the opening 27. To the shafts 8 and 23 are attached a minute hand 28 and an hour hand 29 respectively and the hub 17 carries 25 a day indicating hand 30. Slidably mounted upon the casing 3 and movable by means of a handle 31 is a day-of-the-week dial 32. A slot 33 is provided in the housing 1 for the reception of the handle 31. A glass cover 34 is mounted in the 30 customary position over the face. Mounted within the base portion 2 and adapted to feed into position at the lower part of the face of the clock is a month and year indicating mechanism, consisting of a roll of suitably printed indicia 35, 35 perforated as shown at 36 for removing portions of the roll whenever it is desired to indicate a new month.

The roll is mounted upon a spindle 37 supported by a pair of vertical members 38 and provided 40 with a handle 39. A pair of actuating rollers 40 is mounted above the spindle 37.

The rollers are preferably covered with rubber or other yieldable material and one of them is preferably tubular in structure and is provided 45 with a handle 41.

The roll 35 is adapted to pass between the rollers 40 and to be frictionally engaged thereby for moving the roll into position.

As preferably constructed, one side of the roll 50 is uniformly cut so that the edge 42 always registers with one edge of the numeral 1 of a dayof-the-month indicating portion 42a of the face 6, whereas the other side is variously cut in order that the edge 43 may hide from View such day-of- 55 the-month numerals as a particular month lacks.

In a suitable framework 44 of the base portion 2 a drawer 45 is provided and its bottom is slotted as shown at 46 so that it may not interfere with the vertical members 38.

In operation, the main shaft 8 is driven at the rate of one complete revolution each hour by means of the conventional electrical clock mechanism 4. It will be seen that the minute hand 28 will likewise make one complete revolution every hour, indicating the exact minute upon a dial 47; that the hour hand 29, through the operation of the train of gears 18, 19, 21, and 22, will completely traverse a circle every twenty-four hours, thus indicating the particular hour of the day or night upon a dial 48; that the day indicating hand 30 will move one space each day on the day-of-the-month indicating portion '42ar until the required number of daysin the particularl month have passed, whereupon the day-of-theweek dial may be reset by moving the handle 31 in the slot 33 and the hand 30 may be manually moved forward to the place indicating the first day of the next month.

It will also be seen that the dial 24 will be completely revolved once every twenty-eight days so that the stage of the moon will always be automatically displayed in the opening 27. A handle is provided for starting the motor after the plug 4b has been inserted in its socket.

Although I have illustrated only one form which my invention may assume, and have described that form in detail, it will be apparent to those skilled in the art that the invention is not so limited but that various minor modcations may be made therein without departing from the spirit of my invention or from the scope of the appended claim.

I claim:

In a clock mechanism, an annular dial for indicating the days of the month, an irregularly shaped web bearing month and year indicating indicia and having perforations for the removal of sections of the web, a spindle for storing the web and a pair of actuating rollers for advancing the web over the face of the dial to cut from view certain of the indicia thereon.
